Hi
I am off skiing next week so thought I best help you out!
I am a size 14 (32.5) and managed to get some boots from a shop in Devon (Devon Ski @ http://www.devonski.co.uk/). The guy there had about 5 pairs in stock in a size 32 - 33. I would suggest giving them a call - they were really helpful with me, I was in the shop for about 2 hours trying them on and getting the fit right.
DONT BUY ONLINE - Unless you know your exact boot/size already. The fit varies so much it isnt worth the risk. For example, I tried on a size 33 which felt smaller than a 32.
I got a pair of Rossingol's for £120, custom fitted in store as well.
We have paid for all of our hire already but Thomson couldnt guarentee the size and therefore if I got there and they had no boots, I would be sitting in the hotel all day... not a risk I was willing to take.
Hope that helps anyway.
Karl
